NORTHUMBERLAND, N.H. — New Hampshire State Police say a laboratory analysis of items found in a woman’s car in Northumberland has determined that they contained the drug fentanyl, and not carfentanil, which is 100 times more potent.

Police issued a news release on Tuesday saying 27-year-old Jacqueline Haas, of Northumberland, was stopped by a trooper Saturday night for an apparent equipment violation. Police said an investigation led to the discovery of what they believed to be carfentanil. Haas was arraigned on drug possession charges.

On Thursday, police said the State Police Forensic Laboratory analyzed some items seized from the car and said they were found to contain fentanyl. Police said more items still need to be analyzed and the investigation is ongoing.
